Within this article, we propose a practical and methodological reflection on the analysis of a Twitter corpus, that we consider as a complex corpus because of its particular features (the presence of text and datasets). We will link this corpus to two more traditional ones: a parliamentary debate and some newspaper articles about gay marriage in France. A quantitative and qualitative model analysis has been experimented on a corpus related to the French debate centered on the formulation “marriage pour tous” (marriage for all). , We treat the hashtag as a ‘formula’. We want to build a model for new methods on discourse analysis.
